“…The Vuong test is distributed asymptotically as a standard normal, thus, values larger than the critical

the significance level) favor model j , negative values
are in favor of model k and Vuong ≤
indicates no significant differences between the two models. Nevertheless, in a hedonic price approach, explanatory variables are commonly introduced as dummy variables, thus the use of the semi‐logarithmic form is very common in many agri‐food studies (Bissinger & Herrmann,
